Microsoft is continuing to bolster SharePoint Server 2016. The company has rolled out the January 2017 Cumulative Update for the platform in two KB releases. SharePoint Server 2016 was released as RTM in March last year and has also sent out Feature Pack 1 in November.

This new Cumulative Update comes with Feature Pack 1 and two KB releases, KB3141486 and KB3141487. The first of those updates focuses on adding a security patch to fix a known vulnerability. This issue allowed arbitrary code to run when an infected file is opened. The second KB release brings numerous performance improvements

SharePoint Server 2016 also gets a large number of additions from Feature Pack 1. Among the improvements are:

Administrative actions logging – Admins can now conduct logging around important administrative actions. Microsoft says this helps prevent failures when troubleshooting changes to on-premises environments. This feature will help multi-admin organizations, the company adds. Administrative actions logging works though the SharePoint Server 2016 Central Administration website or through the SharePoint Server 2016 Management Shell.

MinRole enhancements – MiniRole is a farm topology in SharePoint Server 2016. With the new improvements, customers can deploy performance. The feature provides a number of predefined server roles and makes sure services run on the correct farm servers.

Of course, there is much more going on, so here is the full changelog for KB3141486 the January Cumulative Update:

  • Some terms are translated into multiple languages to make sure that the meaning is accurate.
  • You can’t access the Shortcuts link through keyboard in grid edit mode of a SharePoint task list. Additionally, screen readers can’t read or access information panels in SharePoint Server 2016.
  • The PSConfig tool may recommend incorrect cmdlets.
  • Sometimes, the PSConfig tool shows the upgrade as 100 percent completed even though it still takes some time before the tool moves to the next status. This problem occurs because the tool must complete some minor steps after it upgrades the products. Progress messages are displayed for these steps.
  • Fixes the following cmdlet legacy issues of the Administrative Actions Logging feature:
  • Support partial execution for the cmdlet and update the help document correspondingly.
  • Refine the messages for some exceptions and logs.
  • After you try to configure and use the Lotus Notes connector for SharePoint Server, the crawl fails.
  • You can’t use the CSOM API to set the BookingType property for enterprise resources in projects.
  • A system access control list (SACL) isn’t read correctly for large file paths that exceed the Windows limitation of 260 characters. This causes the SACL to be discoverable by any user in the query results even if the user doesn’t have the appropriate permissions.
  • After you make multiple changes to the same user in quick succession in SharePoint Server 2016, the Quick Sync job can’t be completed successfully.
  • When you configure hybrid taxonomy, the specified Local Term Store Name parameter is now case-insensitive even though it was previously case-sensitive.
  • You can’t restore site collection that have site URLs. Additionally, you receive the following error message – Error: Violation of PRIMARY KEY constraint ‘PK_SiteUrlMap’. Cannot insert duplicate key in object ‘dbo.SiteUrlMap’
  • When you add a subtask to an existing subtask of a SharePoint task list, multiple subtasks are created instead of just one subtask, in certain conditions.
  • When you copy and paste subtasks in grid edit mode of a SharePoint task list, multiple subtasks are created unexpectedly.
  • SharePoint Server 2016 becomes unresponsive and the server experiences high CPU usage that requires a restart. Additionally, you can’t access sites, or you get extremely slow page load times.

This security update also contains improvements and fixes for Project Server 2016:

  • When you apply status updates in PWA, actual work is added to some assignments unexpectedly. For example, you have an assignment that has 35 hours total work, and the status update is to apply 9 hours. When you view the results in Project Professional, you find that the assignment is unexpectedly completed. Meanwhile, the total work and the actual work have increased to 400 hours.
